Compare your tax liability under current law vs the Biden tax plan proposals including the 39.6% bracket, capital gains changes, and NIIT.
The Biden administration proposed significant changes to the federal tax code that would primarily affect higher-income taxpayers. Key proposals include restoring the top marginal income tax rate to 39.6% (from the current 37%), taxing capital gains at ordinary income rates for those earning over $1 million, and various modifications to business and investment taxation.
These proposals represent the most substantial potential tax changes since the Tax Cuts and Jobs Act (TCJA) of 2017. While the TCJA lowered individual rates and expanded the standard deduction, the Biden plan would partially reverse these changes for taxpayers above $400,000 in income. Understanding the potential impact is crucial for high-income tax planning.
This calculator lets you compare your estimated federal tax under current law versus the Biden tax proposals. It models the ordinary income brackets, capital gains rate changes, and the Net Investment Income Tax (NIIT) to give you a comprehensive side-by-side comparison. Check the example with realistic values before reporting.
Tax planning requires understanding potential policy changes. This calculator helps high-income earners, financial advisors, and business owners model how proposed tax changes could affect their liability and plan accordingly.

Biden Top Bracket: 39.6% on income above $400,000 (single) Current Top Bracket: 37% on income above $609,350 (single) Biden Capital Gains: Ordinary rates for income > $1M NIIT: 3.8% on investment income above $200K (unchanged)
Result: $145,800 (Biden) vs $139,500 (current)
A single filer with $500,000 income would see an increase under the Biden plan due to the restored 39.6% bracket applying above $400,000, resulting in approximately $6,300 more in federal taxes.

Primarily individuals earning over $400,000, high capital gains/dividend earners (over $1M), and certain corporations. Most taxpayers below $400,000 would see little to no change.
The Biden plan proposes restoring the top marginal rate to 39.6%, up from the current 37% enacted by the TCJA.
For taxpayers with income over $1 million, long-term capital gains would be taxed at ordinary income rates (up to 39.6%) instead of the current maximum of 20%.
Tax proposals require Congressional approval. The timeline depends on legislative action. Any enacted changes may have delayed effective dates.
The core proposals do not change the standard deduction amounts, though TCJA expiration in 2025 could affect deduction levels independently. Use this as a practical reminder before finalizing the result.
The 3.8% NIIT on investment income above $200,000 remains unchanged under the Biden proposals, though some plans expand its application to active business income.
